Detection and Quantification of Heme and Chlorophyll Precursors Using a High Performance Liquid Chromatography (HPLC) System Equipped with Two Fluorescence Detectors
Authors:  Jan Pilný, Jana Kopečná, Judith Noda and Roman Sobotka, date: 02/05/2015, view: 4154, Q&A: 0
Intermediates of tetrapyrrole biosynthetic pathway are low-abundant compounds, and their quantification is usually difficult, time consuming and requires large amounts of input material. Here, we describe a method allowing fast and accurate ...
Radiolabeling of Chlorophyll by [14C]Glutamic Acid in vivo and Relative Quantification of Labeled Chlorophyll by Using Thin Layer Chromatography (TLC)
Authors:  Roman Sobotka, Luděk Kořený, Jana Kopečná and Miroslav Oborník, date: 08/20/2012, view: 4553, Q&A: 0
This is an accurate method to assess the rate of chlorophyll biosynthesis in vivo in cyanobacteria. Given that labeled glutamate is used as the very early precursor of chlorophyll together with a short pulse of labeling (30 min), this ...
